OI-L-STOVE.

SPECIFICATION forming part of .Letters Patent No. 236,866, dated January 18, 1881.

Application filed April 28, 1880. (No model.)-

To all whom llt may concer/n:

Be it lknown that I, JOSEPH M. WHITMORE, of Hobart, in thecounty of Lake and State of Indiana, have invented certain new and useful Improvements V*in Oil- Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had'to the accompanying drawings, and to letters and gures of reference marked thereon, forming a part of this specication.

Figure 1 is a view of an oil-stove, in perspective, embodying my improvements, with a portion of the oven broken away 5 Fig. 2, an end elevation, showing the oven attachment thrown back. Fig. 3, shows the oven attachment turned down onto the top of the stove vand the drum of the stove tilted back to give access to the wick-tubes 5 Fig. 4, a top view of the stove, the oven attachment being removed; Fig. 5, a vertical transverse section in the plane x x, Fig. 4; and Fig. 6, a detached detail.

Referring to the drawings, A represents the base and oil-receptacle of the stove; B, the drum of the stove; G, the top proper of the same; D, a dead-air platform, and E the oven proper. These parts, other than the drum or drums B, are of a rectangular form when constructed to be used in connection with a double stove, and square when used in connection with a single-cylinder stove.

The top C is composed of sheet metal, is made hollow for the circulation of the heated air, and is provided along the sides and ends with the perforations a for the escape of the heated air. The hollow top O is also provided with circular openings, as shown in Fig. 4. of the drawings. Into this hollow top are placed the upper ring, 7, and the lower ring, 8, the ring 7 engaging with the upper part of the top C, and the ring 8 engaging with the lower or bottom part of the hollow top G as shown in 45 Fig. 5 of the drawings'. The lower ring, 8, is provided with the annular depression a for the reception of the ring A. (Shown in Fig.

6 of the drawings and represented by dotted lines in Fig. 5 of the drawings.) This ring 8 is also provided with the downward-projecting 5o part B', which is adapted to engage with the inner circumferential surface of the upper end of the drum B, as shown in Fig. 5 of the drawings. The rings 7 and 8 are secured in place relatively to each other by means of the bolts 9. The lugs 9 are formed integral with the upper ring, 7, and project downward therefrom, the lower ends resting on the upper side of the ring 8. The lugs 9 serve to strengthen these parts and keep the rings the required 6o distance apart. The lower ring, 8, is formed with the diaphragm 10, provided with oblong apertures for the upward passage of the heat, and the spurs l1, which provide a rest for the culinary utensils. The rings 7 and 8 are com- 65 posed of cast-iron, and are inclosed by the sheet-metal casing forming the top O.

The oven-box H is hinged to the back side of the top G, and when used as an oven is turned down onto the top C, which forms a 7o bottom for the same, as shown in Fig. 3 of the drawings, and when the oven is not in use it is easily turned back out of the way, and assumes the position shown in Fig. 2 of the drawings. To the back part of the oven are attached the self-adjusting legs 12, which support the oven when turned back, and also support the drum or drums of the stove when the same is tilted back, as shown in Fig. 3 of the drawings. The legs 12 automatically assume 8o a supporting position relative to the parts to which they are attached. Attached to the front part of the oven is the handle or handgrasp 14, by means of which the oven may be conveniently raised and lowered.

The dead-air platform D is composed of lsheet metal, and should be about one inch in thickness. This platform is hollow, and is intended to be substantially air-tight, in order to prevent a circulation of air through the 9o same, thereby causing the air occupying the hollow space in the platform to remain inactive and act as a non-conductor of heat. This platform D is intended to be used more especially in connection with the oven attachment, and when in use is arranged as shown in Fig. l of the drawings. This platform D is for the purpose of preventing a direct radiation of the heated air to the under side of the article of food being roasted or baked, as without this platform the under side of the article being cooked would be burned before the upper part was done through. The platform D is provided at the ends with downwardly-projecting anges, which act as legs and serve to elevate the platform a little above the immediate top of the stove, so as not to interfere with the combustion of the same, and allow the heat to pass upward on each side of the platform D.

The oven H has no openings in the top for the escape of the heat, but retains the heated air in a dense body, thereby surrounding the article being cooked by a steady and uniform heat and thoroughly cooking the same on all sides alike.

The ordinary oven attachment commonly used in connection with oil-stoves is usually provided with one or more perforatious in the top for the escape of the heat, which forni of construction has the effect of causing a draft through the oven, and it is obvious that the upper part of the article of food cannot be thoroughly and evenly cooked.

By the use of my oven attachment in connection with the dead-air platform I am enabled to cook an article of food in much less time than it is possible to do when making use of the ordinary oven attachment for oilstoves, and at the same time equally distribu ting the heat, as the heated air can only escape from the oven around the base ofthe same.V

The ring A (shown in Fig. 6 of the drawings) is made to set into the top of the stove, in the manner illustrated by the dotted lilies in Fig. 5 of the drawings, for the purpose of throwing all the heat upward, instead ofallowing it to pass out through the perforations a in the hollow top C. The lower edge of this ring lits into the annular depression a in the lower ring 8, and the flange or rim 15 ofthe ring A rests upon the upper part of the casing forming the top C.

The latch 16, attached to the drum of the stove. is adapted to engage with the catch 17, attached to the base of the stove, for the purpose of securing or locking these parts together relatively to each other.

The upper and lower ends of the drum B are permanently secured together by means of the screw-bolt 13, as shown in Fig. 5 of the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an oil-stove, the combination, substantially as described, of the hollow sheet-iron top C,a|1d the drum or drums B, and the castmetal rings 7 and 8, connected, constructed, and arranged as herein shown and described.

2. In an oil-stove, the deadair platform D, substantially as and for the purpose described.

3. In an oil-stove, the combination of the hollow top C, and the hinged close oven attach ment H, and the dead-air platform D, substantially as shown and described.

4. An oil-stove of the character liereinbefore described, consisting, essentially, of the following element-s: the base A, drum or drums B, the hollow top U, the cast-metal rings 7 and 8, connected as described, the dead-air platform D, the close oven attachment H, and the self-adjusting legs 12, all constructed, arranged, and operating in the manner and for the purpose set forth.
